An Access parameter query is a simple yet highly effective type of query in Microsoft Access. It allows you to dynamically update the data by entering a value when prompted, making it ideal for performing targeted searches within your database.
When designing a parameter query, avoid using a prompt that is identical to a field name. For example, using [LastName] as a prompt to enter a value into the LastName field will not work because Access interprets square brackets as field references. A simple workaround is to use a slightly different prompt, such as [LastName?], to prevent conflicts and ensure the query functions correctly.
